Refined and Sporting Diesel Power
The introduction of an all-new, state-of-the-art V6 diesel
engine marks yet another milestone in the evolution of Jaguar's
S-TYPE premium executive saloon.
The arrival of the twin-turbo AJD-V6 engine means that, for the
first time,
S-TYPE buyers will be able to choose diesel power as an alternative
to the existing petrol 3.0 V6, 4.2 V8 and 4.2 V8 supercharged
engine options.
The addition of an advanced 2.7-litre turbocharged diesel V6 is
one of several improvements in the new S-TYPE. Striking styling
changes including a new rear-end design and a new aluminium bonnet,
dynamic improvements, enhanced interior features and a wider choice
of equipment, are among the highlights of a package of revisions
announced in 2004.
Embracing diesel in the S-TYPE is a natural progression for
Jaguar, with diesel engines now able to deliver the refined
performance customers of the marque demand. The all-new AJD-V6 is a
superb example of a state-of-the-art diesel engine and complements
perfectly the advanced technical attributes and sporting character
of the S-TYPE.
The engine's specifications make for impressive reading. The
four-cam, 24-valve, twin-turbo V6 features second-generation
common-rail direct injection and super-fast piezo-electric injector
operation. Maximum power from the 2.7-litre engine is 153kW. Torque
peaks at a heady 435Nm, which is actually higher than that of the
S-TYPE's naturally aspirated 4.2-litre V8 petrol engine. Yet the
diesel has 47 percent better fuel consumption. More crucially
still, 80 percent of this torque is available from just 1500rpm
through to 4000rpm.
This combination of substantial power and torque gives the new
S-TYPE Diesel huge mid-range flexibility and refinement. True to
Jaguar tradition, it is relaxed when cruising, yet pleasingly rapid
cross-country - characteristics which are accentuated by a
six-speed automatic transmission. Jaguar's S-TYPE Diesel offers
very accomplished performance: the benchmark 0-100km/h sprint in
8.6 seconds. Top speed is 227km/h.
The S-TYPE Diesel also addresses environmental challenges; its
CO2 emissions of 208g/km with automatic transmission. Combined fuel
efficiency is 7.8L/100km, while in the highway cycle achieves
6.2L/100km. The model-year 2006 S-TYPE Diesel is Euro Stage IV
emission compliant.
Why Diesel?
The diesel market in Europe has experienced consistent - and
significant - growth over the past decade. In recent years, demand
for diesel has increased dramatically in the premium market. Diesel
now accounts for approximately 40 percent of sales across the
premium segment in Europe.
The AJD-V6 Engine
As with all engines in the Jaguar line-up, the AJD-V6 has
benefited from the expertise of engineers at the company's Whitley
Engineering Centre. Delivering the performance and refinement that
customers expect - and demand - is key to the success of any
Jaguar. The new S-TYPE Diesel is no exception.
"Strong performance is an inherent characteristic of the new
V6 Diesel engine, but the accompanying levels of refinement are
even more impressive. I am proud that the Jaguar Product
Development team at Whitley has done an excellent job."
Phil Hodgkinson, Jaguar Programmes Director
The diesel-engine S-TYPE is offered in Australia with only the
six-speed ZF automatic. The transmission is developed to maximise
both the performance and great flexibility of the twin-turbo V6
engine.
The 2.7-litre diesel engine will also be used in other
applications, in line with the co-operative agreement on diesel
technologies and development between Ford Motor Company and PSA
Peugeot Citroën. However, S-TYPE owners will benefit
particularly from the exceptional Noise, Vibration and Harshness
(NVH) performance resulting from the efforts of Jaguar's engineers
at Whitley.
Achieving an engine installation that satisfies or exceeds all
engineering requirements is easier if the engine itself is
exemplary and the all-new 2.7-litre AJD-V6 can lay claim to that
accolade. Not only does it have class-leading specific power
outputs, but the use of compacted graphite iron (CGI) in the engine
structure ensures outstanding strength, durability and - of
particular relevance in a diesel engine - low weight.
Because less material is needed to construct a CGI block than a
conventional cast iron block, the engine can be both lighter and
shorter. The result is that the engine in the new S-TYPE Diesel is
the lightest unit of its type and size. It weighs just 202kg - only
15kg more than the equivalent petrol V6 engine.
In short, the new S-TYPE has a new diesel engine that provides
exactly what Jaguar customers want: the best engine in the best
car.
Summary
The all-new diesel model is a logical and welcome addition to
the new S-TYPE range. It complements perfectly the 3.0-litre V6 and
4.2-litre V8 models, offering S-TYPE customers the choice of diesel
power without sacrifice.
"The new S-TYPE Diesel delivers on all levels. Not only does
it have the performance and dynamic abilities for which Jaguars are
renowned, it also offers exceptional refinement and flexibility.
This is a great engine in a great car."
Paul Walker, Chief Engineer, S-TYPE, Jaguar Cars
As with the rest of the range, the new S-TYPE diesel boasts
attractive costs of ownership to appeal the premium segment buyer
who expects strong value for money as well as style and performance
- even from a luxury marque.
But perhaps most crucially, S-TYPE Diesel retains its unique
Jaguar personality: a combination of bold, athletic styling,
driver-focused performance, outstanding comfort and refinement, and
unrivalled emotional appeal underpinned by outstanding driving
dynamics.
